Umehluko Womthombo Wokukhanya we-80WCOB

Ngesikhathi senqubo yokusetshenziswa, ukulimala kwejeli (okwenziwa ebusweni be-collagen) kubangele ukuthi umugqa wegolide wangaphakathi unqanyulwe futhi isibani esifile (njengoba kuboniswe esithombeni esiboniswe esithombeni) kwenzeka. Isendlalelo sesakhiwo se-LED esisekelwe ku-GAN siyakhula ku-substrate ye-Lan Gold, futhi ukukhanya okukhishwa indawo yokukhanya kwezinwele ye-P/N kudutshulwa endaweni emise okwe-P ngenhla. Ngenxa yokungasebenzi kahle kokuqhutshwa kwe-P-type GAN GAN, ukuze uthole ukunwetshwa okuhle kwamanje, kuyadingeka ukwakha ungqimba lwe-NI-AU ebusweni bendawo ye-P ngokusebenzisa ubuchwepheshe be-steam. Indawo ye-porn P iholwa yilolu ngqimba lwefilimu yensimbi. Umthombo wokukhanya we-COB wubuchwepheshe bomthombo wokukhanya okhanyayo obuphezulu obuxhumeke ngqo esibukweni sensimbi esingaphansi se-chip ye-LED ngqo ekukhanyeni okuphezulu okubuyela emuva. Okokuqala, izindleko nazo zigcinwa ngokukodwa kokuthathu. Ngokuvamile, izibani ezithuthuke kakhulu futhi ezidonsa amehlo kunezibani ze-LED. Phakathi nenqubo yokushisela, ezinye izinto zinamathele ebusweni be-colloid ukuze kulimaze i-collagen isikhathi eside. Uyini umthombo wokukhanya we-LED? Abangane abangawazi lo mbuzo bavame ukucela abangani abajwayelene ne-projektha. Uma kuqhathaniswa nemithombo yokukhanya yendabuko, ivolumu yemithombo yokukhanya ye-LED incane. Ngakho-ke, kukhona ukuqagela okuncane okuningi okuhlakaniphile emakethe manje. Umphumela wokukhanya wesimo esingaguquki ubhekisela esilinganisweni sesilinganiso se-flux yokukhanya namandla kagesi akalwa lapho izinga lokushisa le-chip knot lingasakhuphuki nokukhanya kuqinile uma ukukhanya kunamandla lapho umsebenzi womthombo wokukhanya we-LED ungena ekuzinzeni kwe-thermal. Umphumela wokukhanya we-steady -state ubhekisela emiphumeleni yokubona yezibani zizonke ze-LED ngaphandle kokushayela ugesi, okubonisa izici eziphelele zokukhanya, ugesi, kanye ne-thermal emsebenzini wangempela we-LED. Ngokungeziwe ekukhanyeni kwesikhashana kwe-LED nokukhethekile kukagesi, umphumela wokukhanya wesimo esiqinile uhlanganisa nokushintsha kwezinga lokushisa lokudlulisa ukushisa kwesistimu kanye nokunqanyulwa kokushisa. Kwaziwa nangokuthi ukukhanya kwesistimu. Inkomba yokunikeza umbala yokukhanya kwelanga ichazwa ngokuthi 100, futhi inkomba yokunikeza umbala yamalambu e-incandescent isondelene kakhulu nokukhanya kwelanga, ngakho ithathwa njengomthombo wokukhanya ofanelekile. Le sistimu ihlolwe ngamasampula ombala ajwayelekile angu-8 -chroma medium and medium-sized. Uma kuqhathaniswa nezinga lokuchezuka (Ukuchezuka) kumthombo wokukhanya wokuhlola nezinga lokushisa lombala ofanayo, ukukala inkomba yokunikeza umbala yomthombo wokukhanya, thatha inani lokuchezuka elimaphakathi elingu-RA20-100, elingu-100 njengokuphezulu kakhulu, okukhudlwana umehluko wombala omaphakathi, inani eliphansi le-RA. Imithombo yokukhanya engaphansi kwama-20 ngokuvamile ayifanele ukusetshenziswa okuvamile. Umthombo wokukhanya we-80WCOB empeleni yingoba umthombo wokukhanya we-LED wamukelwe. Ngakho-ke, kungaba khona inzuzo yevolumu enjalo. Umthombo wokukhanya we-bulb yendabuko udinga isikhala esikhulu ukuze ukhiphe ukushisa. Khetha lo mthombo wokukhanya we-LED wamahhala, umthombo wokukhanya we-COB ungaqondakala kalula njengemithombo yokukhanya engaphezulu kwamandla ahlanganisiwe. Ungakwazi ukuklama indawo yokukhanya kanye nosayizi womumo womthombo wokukhanya ngokuya ngesakhiwo somumo womkhiqizo. Indlela yendabuko yokufaka uphahla Umkhawulo wokukhanyisa: umsebenzi wokukhanyisa unqunyelwe indawo yokuklama nendawo yokufaka yomthombo wesibani, ngakho-ke kufana nokushoda; umthombo wokukhanyisa kanye nesitayela somhlobiso wangaphakathi asihambisani, akukho mqondo womklamo wokukhanyisa. Inzuzo yokukhanyisa ophahleni ehlanganisiwe: Esimeni semojula ye-MSO, ukukhanyisa kungabekwa ngokungafanele kunoma iyiphi indawo yegumbi ukuze kuzuzwe umphumela oyifunayo. Uhlelo oluphelele lokuklama ukukhanyisa aluhlinzeki nje ngemiphumela yokukhanyisa eyenziwe ngabantu, kodwa futhi luthuthukisa kakhulu umphumela wokuhlobisa. Ukukhuluma nje, i-COB ivamise ukusho ukupakishwa kwe-chip encane noma yamandla amaphakathi. Ngokuvamile, amandla ewonke aweqi ku-50W, futhi umthombo wokukhanya ohlanganisiwe uvamise ukufakwa ama-chips anamandla amakhulu. Amandla esewonke avamise ukuba ngaphezu kuka-50W noma ngaphezulu. Umthombo wokukhanya we-80WCOB COB (CHIP on Board) owokulungisa i-chip ngeglue esiliva ku-substrate.
